I am definitely doing three year only vaccinations at most for both dogs and cats from now on; I've only got one more annual booster to do for one cat then they all have the basic set. I've talked about the whole vax issue with other animal-oriented people, read the literature, and talked to my dad (retired prof of (human) medicine) and feel fewer vaccinations make health sense.

You should decide whether your dog needs that vaccination

By Nancy Kerns

Most dog owners are responsible and understand the importance of protecting their companions from preventable disease. ThatĂ˘â‚¬â„˘s surely what motivated the dozens of people I observed standing in a long line with their dogs and puppies at a low-cost vaccination clinic offered in a local pet supply store.

Which vaccines should your dog receive? It is your responsibility to determine the real risks of the diseases they are supposed to defend your dog against, and weigh the potential benefits of vaccination against the potential harm.

In addition to vaccinations, the veterinary business running the clinic also offers flea and tick treatments, heartworm tests and preventive medication, and identification microchip implanting, so at the head of the line, a young man in a white coat and holding a clipboard asked each client what she wants for her pet. Dozens of times, I heard an owner say something like, Ă˘â‚¬Ĺ“Well, we just got him, so I want to get whatever shots he needs.Ă˘â‚¬Âť It was a tense moment for me every time I heard this, since I was aware that the clinic had available for sale far more vaccines than the dogs and puppies standing in line were likely to Ă˘â‚¬Ĺ“need.Ă˘â‚¬Âť

No universal protocol
Many dog owners are surprised to learn that there is no single, universally accepted canine vaccination schedule. Most trust their veterinarians to give their dogs whatever vaccinations the vet recommends Ă˘â‚¬â€ś and many vets recommend more vaccinations than most dogs require in order to be protected from contagious disease.

This can probably only rarely be accurately attributed to opportunism on the part of the vet. Most vets use the vaccination schedules they receive with the vaccinations they buy from drug companies.

Historically, this was a sound choice. For decades after the first veterinary vaccines were developed, veterinarians and government regulators alike trusted the companies that studied, developed, and manufactured the lifesaving vaccines to recommend appropriate schedules for their use. Today, though, they are realizing their trust of the vaccine makers may have been slightly overextended for a decade or two.

You see, vaccine makers are in the business of selling vaccines. So it follows that most of them recommend that their vaccines be administered annually Ă˘â‚¬â€ś despite the fact that independent studies have shown that many vaccines convey immunity from disease for many years, if not the lifetime of the dog.

In a policy statement about vaccines, the American Veterinary Medication Association (AVMA) acknowledges, Ă˘â‚¬Ĺ“The one-year revaccination frequency recommendation found on many vaccine labels is based on historical precedent and United States Department of Agriculture regulation, not on scientific data. Even in those cases where scientific data was submitted to qualify the label claim, the data generated does not resolve the question about average or maximum duration of immunity.Ă˘â‚¬Âť

For a long time, the few experts who realized dogs may receive far more vaccines than they needed were not particularly worried. Ă˘â‚¬Ĺ“It canĂ˘â‚¬â„˘t hurt Ă˘â‚¬â„˘em!Ă˘â‚¬Âť But in the late 1980s, as medical science learned exponentially more about the immune system, proof began to turn up that repeated vaccinations could have deleterious effects on companion animals.

Today we know that adverse events may be associated with the disease antigen, the adjuvant (an agent added to increase or aid the effect of the antigen), carrier substance, preservative, or a combination of any of these. The AVMA vaccination policy statement says Ă˘â‚¬Ĺ“Possible adverse events include failure to immunize, anaphylaxis, immunosuppression, autoimmune disorders, transient infections, and/or long-term infected carrier states.Ă˘â‚¬Âť

To their credit, when vaccines can be directly linked to specific, reproducible injuries or illnesses, the vaccine makers (and regulators) leap to study the problem, as in the case of vaccination site-associated feline sarcoma. Unfortunately, the problems experienced by dogs that many practitioners and researchers suspect may be linked to overvaccination are all over the map. Some suspect excessive vaccines are linked to the increased incidences of many diseases, including cancer, epilepsy, severe allergies, thyroiditis, autoimmune hemolytic anemia, AddisonĂ˘â‚¬â„˘s disease, and even behavioral problems such as aggression.

Get information
Fortunately, educated owners can do a number of things to make sure that their dogs are adequately protected against disease, without overvaccinating.

There are canine vaccines for more than two dozen diseases, with many vaccines available in combinations with others. Very few dogs are at risk for all or even most of the diseases. So the first step is to learn about the diseases the vaccines are designed to defend your dog against.

Before agreeing to any vaccination, ask your vet about the disease it prevents. What is its incidence? How is it transmitted? Is it more prevalent in some climates or parts of the country than others? Is the disease treatable, and if so, how many dogs recover? Then you can extrapolate the answers to your dog and locale.

If you learn that the disease kills many dogs who contract it, and the virus is everywhere, well, you probably authorize that vaccine, right? But if you lived in a city apartment with a Papillon who didnĂ˘â‚¬â„˘t so much as visit parks, a vaccination for a tick-borne disease like Lyme is really not needed.

Today, most veterinarians discuss vaccines in terms of Ă˘â‚¬Ĺ“coreĂ˘â‚¬Âť versus Ă˘â‚¬Ĺ“non-coreĂ˘â‚¬Âť products. Core vaccines are those that can protect your dog from the diseases that are widely distributed in your part of the country, virulent, and highly infectious. Think of them as the vaccines with the highest benefit to risk ratio. Non-core vaccines are those that are intended for a minority of dogs in special circumstances. They may target diseases that are of limited risk in your area, or those that present only a low-level threat to your dogĂ˘â‚¬â„˘s health.

Ă˘â‚¬Ĺ“CoreĂ˘â‚¬Âť vaccines
These are the vaccines for diseases that most experts agree puppies and dogs should be protected against Ă˘â‚¬â€ś diseases that are highly contagious and potentially fatal.

Ronald D. Schultz, PhD, is department chairperson and a professor at the School of Veterinary Medicine, University of Wisconsin in Madison. HeĂ˘â‚¬â„˘s also one of the countryĂ˘â‚¬â„˘s leading experts on veterinary vaccines, having performed research for or with literally every veterinary vaccine company in the U.S. WeĂ˘â‚¬â„˘ll use Dr. SchultzĂ˘â‚¬â„˘s list of Ă˘â‚¬Ĺ“coreĂ˘â‚¬Âť vaccines for dogs:

For what people commonly refer to as Ă˘â‚¬Ĺ“puppy shots,Ă˘â‚¬Âť many veterinarians use a combination vaccine that contains antigens for distemper, hepatitis, leptospirosis, parainfluenza, and parvo (referred to by its initials, DHLPP). If you are concerned about overvaccination, ask your veterinarian if she can vaccinate your puppy against just parvo, distemper, and adenovirus (the rabies vaccine is usually given separately later, after the puppy is 16 weeks old). A vet can purchase and use individual vaccines, but she may have to buy them in bulk, and wonĂ˘â‚¬â„˘t be happy about it if you are the only one in her practice who wants them.

Most experts agree that puppies should be vaccinated against distemper, parvo, and adenovirus, not before six weeks, and at least once after the age of 12 weeks; the rabies vaccine is given after 16 weeks. About two weeks after the last vaccination with distemper, parvo, and adenovirus, ask for a vaccine titer test to confirm your puppy has been successfully immunized (see Ă˘â‚¬Ĺ“Titer Tests: A Terrific ToolĂ˘â‚¬Âť sidebar).

Ă˘â‚¬Ĺ“Non-coreĂ˘â‚¬Âť vaccines
Then there are the non-core vaccines. Some (including Dr. Schultz) refer to all the other vaccines that are available as non-core, suggesting that these be given only to dogs that need them, and only as often as needed. For these vaccines, the ratio of benefits to drawbacks is less weighted toward the benefits Ă˘â‚¬â€ś at least for most dogs.

A good example is leptospirosis. The duration of the immunity typically conveyed by the lepto vaccine is generally less than one year, so to convey optimal protection from this disease, it must be given at least twice a year, every year. Also, the vaccine used must contain all four strains of the disease that are currently available to vaccine makers, because the strains do not provide cross-protection. Lepto poses a very minimal risk in many regions of the U.S. And where it is more common, there have been recent reports of new strains emerging, for which there are no vaccines yet.

All of this suggests that administering the vaccine would benefit only those dogs living in an area with a current, high rate of infection Ă˘â‚¬â€ś and only if they are properly vaccinated at frequent intervals with all the available strains.

Ă˘â‚¬Ĺ“Not recommendedĂ˘â‚¬Âť vaccines
Some experts classify some vaccines in a third category of Ă˘â‚¬Ĺ“not recommended.Ă˘â‚¬Âť These would include any vaccine for which they perceive to be no realistic benefit.

For example, there is now a vaccine against giardia, which is a protozoan intestinal organism that dogs may be exposed to when drinking out of ponds or streams. Many veterinarians feel that despite the marketing efforts behind the vaccine, giardiasis poses little risk to most dogs.

Many experts also doubt the usefulness of the coronavirus vaccine. According to Dr. Schultz, Ă˘â‚¬Ĺ“To date, no one can demonstrate a benefit for coronavirus vaccine.Ă˘â‚¬Âť

Other vaccination tips
When they learn that overvaccination may be harmful to their dogs, many people ask, Ă˘â‚¬Ĺ“Why would my veterinarian suggest doing something that could hurt my dog?Ă˘â‚¬Âť The fact is, information about the potential risks of overvaccination is fairly new. Veterinary colleges, the AVMA, and the American Animal Hospital Association (AAHA) have changed their suggested vaccination schedules in only the past few years.

A few final vaccination tips:

Ă˘â‚¬Â˘ Use vaccine titer tests to determine whether your dog is adequately immunized against the core diseases. (For more detailed information, see Ă˘â‚¬Ĺ“Taking the Titer Test,Ă˘â‚¬Âť WDJ December 2002).

Ă˘â‚¬Â˘ DonĂ˘â‚¬â„˘t rely on low-cost clinics for your dogĂ˘â‚¬â„˘s vaccinations. These clinics exist to sell vaccines, not to provide full care or detailed advice. They cannot provide the full hands-on exam that your dog should receive at least once a year, and may not take the time to determine whether a vaccination is contraindicated for your dog. Instead, establish a relationship with a veterinarian who will take the time to examine your dog, ask about his health history, answer questions about the benefits and risks of various vaccines, and recommend an individualized vaccination protocol for your dog that takes your dogĂ˘â‚¬â„˘s health, his lifestyle, and his environment into account.

Ă˘â‚¬Â˘ Do take your dog to your veterinarian at least once a year. A thorough annual (or better yet, semiannual) health examination and annual titer test is the best way to find problems early, before they are difficult and costly to treat. Your veterinarian can also help you develop a sound preventive health program to keep your dog vital to the very end of a long, happy life.

Ă˘â‚¬Â˘ Vaccinations are contraindicated for dogs who are not healthy. Do not vaccinate dogs who suffer from chronic or acute health problems, running a high temperature, or who have a history of vaccine reactions. This sounds simple, but many times people go to the vet for an injury, say, an abscess or to remove an embedded foxtail, and the vet notices the dog is Ă˘â‚¬Ĺ“overdueĂ˘â‚¬Âť for vaccinations. The dog is currently battling a local infection! Do not have him vaccinated at that time.

Ă˘â‚¬Â˘ DonĂ˘â‚¬â„˘t vaccinate elderly dogs. If your dog has been vaccinated many times in his younger years, he is probably as well immunized against disease as he will ever be. Plus, his exposure to disease decreases as he ages and travels and exercises less.

Thankyou so much for this and the link Karlin.
About three years ago after losing a second dog to an Immune problem, I did some research into vaccinations and decided there and then to stop annual boosters.
My dogs at that time were mostly middle aged and I can still remember the awful dilemma of 'how would I feel if?' but I made my decision and have not had any of them boostered since.
If I had a new puppy I haven't decided yet whether I would follow the initial shots and then the first booster and that would be it, or to go with the three yearly regime.
As regards the last paragraph of the post from the journal, my vet stressed it was more important to booster the older dogs as they would be the least able to fight off disease ! Mind you, he has just written to tell me that if I let my annual boosters lapse then I will have to go through the whole process again from scratch!
Ruth

Ruth, I completely disagree with your vet! My Cavaliers are 15, 15 (two littermates) 12 and 12. I also have a 14 year old shih tzu and an 11 year old westie/maltese mix.

I stopped doing annual vaccinations in 1997 after doing much research about the problems of over-vaccination and the suspected link to autoimmune diseases and degenerative diseases (including cancer, IMHA etc.) I ran titers for years, but I don't even do that anymore because there is no way I will vaccinate any dog as old as mine. I am firmly convinced that my dogs have lived much longer than the average in part because of my vaccination policy. I will say that my dogs rarely leave home - no boarding, no shows - occasional visits to friends, so they don't have great exposure. But they are at the vet's office at least every couple of months for bloodwork, etc., so they are exposed there.

(Now my younger dogs do get their core puppy vaccs, a one year booster for core diseases only, and then another one three years later. They also get three year rabies vaccs. I separate the vaccs -- do one every year.)

Ruth -- if my memory is correct, didn't one of your Cavaliers have an incident of vestibular syndrome a couple of years ago? I think we talked about that on another board. I've had three Cavaliers who had had these incidents and all recovered well. (One does have a permanent slight head tilt.) Anyway, good to hear from you again.

I'd always understood that it wad the reveres too -- that by the time a dog reaches middle age it has had more than enough boosters and caxing into old age really stresses the dog's immune system. My dad agreed with this perspective -- not a vet but a medical professor.

I disagree with my vet too. I've never had the oldies boosted since (about four years). One will hopefully be celebrating his 14th birthday next month.

Nice to catch up with you too Pat. I've had two that suffered some kind of Vestibular problem. One had unilateral facial paralysis, head tilt, nystagmus and the other had all of that but bilateral facial paralysis.
The first boy was the one I lost to a total Immune breakdown, he went undiagnosed (even after a post mortem), although we took him to Specialists and the Vet School up in Edinburgh. I'll never get over his loss.
The second boy I still have, he is a half brother to the first one and showed similar symptoms, but thank goodness he has survived, he was eleven last January. It was because of this that I stopped boosters.
